This blog has been abandoned and I want its address

Blogger accounts and Blogspot addresses do not expire. Therefore, we can't take away somebody's blog address to give to you. Occasionally people come back to their blogs after long absences, and we want them to be able to find their blog as they left it. If you find some contact information on the blog, you are welcome to deal with the owner directly, to see if they are willing to transfer ownership so you can use that URL. However, we do not give out contact information for the owner of a blog.
